Patent EP-0451366-A1 (EP)
Inventor: WOLFF GUENTER DIPL-ING FH
IPC: B60T8/40
Filed: 1990-12-22
Abstract: The intake of air into the hydraulic pump is to be prevented if the intake line is absent. 
<??>The hydraulic pump (10) has a connection bore (25) connected to the intake chamber for the sealed accommodation of an intake hose nipple (26) of an intake line (27). In addition the pump (10) has a connection bore (32) for a pressure line connected to the pressure chamber. From the connection bore (25) for the intake hose nipple (26) a duct (connecting bore 31) connected to the pressure chamber of the pump (10) emerges, which is tightly sealed by the intake hose nipple (26) introduced into the connection bore (25). In the absence of the intake hose nipple (26), the pressure chamber of the pump (10) is short-circuited by the duct to the intake chamber. In this way a build-up of pressure in the pump (10) and hence any delivery of air is precluded. 
<??>The hydraulic pump (10) can be used, for example, for vehicle hydraulic brake systems in which, for safety reasons, the intake of air into the brake system must be prevented.

Abstract: The reel according to the invention comprises a first groove (9) and a second groove (13), both formed close to the forward end (3) of the spool support shaft (1). The spool (4) comprises an elastic catch (10) that can engage in either of the first (9) and second (13) grooves. When the spool (4) is engaged in the first groove (9), a catch (18) on the shaft engages in a passage (15) in a rearward wall (14) of the spool, preventing the relative rotation of the spool (4) on the shaft (1). When the elastic catch (10) engages in the second groove (13), the catch (18) spins freely in a space (24) in the spool (4), allowing the relative rotation of the spool on the shaft. The spool is thus disengaged by an axial translational movement of the spool on the shaft (1). …<IMAGE>…

Abstract: Un agencement de poche de coulée destiné à l'usage lors du traitement d'un métal en fusion, au cours duquel du gaz ou un mélange gaz/poudre est apporté au métal en fusion (2) qui remplit sensiblement la poche de coulée (1), et les gaz dégagés sont extraits par succion à travers une hotte montée au-dessus de la poche de coulée. Cet agencement de la poche de coulée est efficace car il permet au gaz ou au mélange gaz/poudre d'être apporté au métal en fusion dans un grand courant volumétrique, avec lequel le métal en fusion bouillonnera et rejaillira vigoureusement. De manière à limiter les effets de ces éclaboussures du métal en fusion à un espace défini au-dessus du métal en fusion (2), la hotte d'extraction de gaz a la forme d'un couvercle (7) destiné à se refermer sensiblement hermétiquement sur le bord supérieur de la poche de coulée (1). Le couvercle est configuré de sorte que le volume (6) délimité par le couvercle au-dessus du métal en fusion corresponde à une partie importante, de préférence au moins la moitié, du volume du métal en fusion (2) dans la poche de coulée (1). Les surfaces latérales du couvercle (7) comportent des rainures servant à rendre les gouttelettes au métal en fusion dans la poche de coulée. L'invention concerne également un procédé de traitement d'une coulée de métal dans une poche de coulée.

Abstract: The method makes it possible in a simple manner to match the energy transfer to the transfer conditions at any given time in devices for contactless transfer of data and energy. For this purpose, the stationary portion (ST) continuously writes a test data word into the memory of the moving portion (BT), reads it out again and compares it with that just written. Starting from a maximum energy supply, the energy supply is now reduced stepwise each time after writing and reading the test data word. If the written test data word and the read test data word no longer agree during the method, the last value set for the energy supply is increased by a safety value and a changeover into the normal operating mode is then made. <IMAGE>

Abstract: A control system for a burner (1) is disclosed which detects oxygen concentration in a room using an oxygen sensor (17), to thereby supply an abnormality detecting signal (S2) to at least one of an alarm (35) and a combustion reducing device (37) to actuate it when oxygen concentration is lowered below a predetermined set value. A first comparing means (25) and a reference value storing means (27) are used to cause maximum oxygen concentration detected to be stored as an oxygen concentration reference value (R1) in the storing means. A second comparing means (31) compares the deviation (D) between the oxygen concentration reference value and a detected oxygen concentration value (S1) with an abnormality judging reference value (R2), to thereby generate the abnormality detecting signal when the deviation is larger than the reference value. The control system is capable of effectively detecting a low oxygen concentration condition without being affected by a temperature of an environment sounding the oxygen sensor.
